" permit the full bobbins to rotate ireely, it'

.be reciprocated forwardly desired, upon the pegs 37.

At the upper extremity o-t each of the lrackvpillars or slides 24 a bracket 41 is lixed by means of a lu or collar 42, said brackets 41 carrying a. siiai't or rod 43 free to be turned in said brackets 41 by` means oi a handledever 44; and at their rear or imier portions said brackets 41 may carry rigidly a bar 45 to be referred to hereafter. The rody 43 carries a secondary rod or rock-shaft 46 by means of armsy or levers 47 which are securely fixed to said rod 43 and which have apertured ree extremities through 'which said rock-shaft 46 gasses and in which said lrook-shaft is adapte to be moved both longiti'idinally and rotatably on its axis by means of a hand-wheel 48 or other suitable device. 'Ihe rod 43, rock-shaft, 4G and har 45 are (therefore all carried by the brackets A41 at the heads of the rack pillars or slidesI 24 and are thus capable. of being reciprocated bodily infront of the machine.

In Order to transfer the caps 7 and full bobbins 13 from the spindles 8 and replace the full bobbins by the empty bobbins 14 and also to replace the caps 7 in position over said ein-pty bobbins 14, a special formy of carrier 49 is employed. This carrier 49 is illustrated in detail in Figs. 10 and 11, and may consist of a horizontal casting liaving an upwardly projecting integral stem 50to which an auxiliary steadying device suc-h as a spring-dil.) 51 is fixed. These carriers support but do Anot grip the ca s or the bobbins. At the rear of each oit said `horizontal castings a lug having a slot 52 is formed whereby said carriers may be attached to a bar 53, earch'. at a point in rear of"a` spindle 8', while, the forward portion or base of said castingconsists of| a .air of horizontal fiat 4limbs or arms 54, 54, marginal upwardly extending flanges 55, 55, and surrounding 4a substantially keyhole-shaped aperture. The bar 53, which' carries'the series of carriers 49 is fixed at each end,l and intermediately also it necessary, to horizontally mounted rack .bars or slides 56 arranged in guides 57 integral with or attached to.tlie-'lianie 1 of the machine, said rack slides` 6 being adapted to and backwardly `within the guides 57 by means of pinions 58 fast upon a shaft 59 extending in suitable bearings longitudinally 'ol' the machine, in

iaving rear of said board or baille 6, and operated by means of a hand-wheelvGO and pinion (31 which meshes with the toothed underside (not shown), of one of the rack-slides 56.

lt is preferable, when the operation of doiling is )er'foi'med in cap-spinning frames, to keep all the yarns or threads 62 to the front o'l,Z the caps lwhere they will not be liable to `foul any of he parts or become entangled as the caps or bobbins are removed from the spindles, and to effect this and also to enable the ends of the'yarns or threads to be secured to the empty boljlbins,what is hereinafter termed thread-'conveyer mechanism employed. comprise a series ot' hooked rods or conveyors (33,' (see lfigs. 1L and 13,) which are mounted, one in front o: each full bobbin 13, upon the aforesaid secondary rod or rock-shaft 4G, which is carried so as to be 85 capable o1 being slid longitudinally as well/U as capable of being oscillated or moved an gula-r y 1n the arms or levers .47, the latter being adapted to he moved angularly by the shaft or rod 43, as described above,

lugs or stops 64 on the brackets 41 limiting said angular movement of the arms or levers 47 in :i direction outwardly of or away Vfrom the machine. The conveyors 63 serve a double purpose and are accordingly of special formation.

One form 'of conveyor is illustrated in Figs. 12 and 13 and a slightly modified 'forni is illustrated in Figs. 14 and 15.

In the form shown in Figs. 12 and 13 100 each conveyor l(53 consists of a rod hooked at its outer end and attached 0r hine'ed at its inner end by means of a pin (So to a bracket (5G secured by a set screw 67 to rod 4G. At its outer formed with a re-curved hooked limb (3S and a cross member 69 bridgiinr the limb 68 and the' body portion 63.0" the coiiveyer, and further, a weight 7() is attached at said hooked outer end of each conveyor beveled o-r angular peg each coi|\eyei" 63. During onestep of the dofling operation these con'veyers 63 are caused. lo rest with pegs 71 upon the lower flanges o'l3` the empty bobbins 14 (Fig. when the latter have been vplaced uponv the spindles S, and the hinged joint 65 which. permits limited angular movement of each eonveyer (S3 relatively to its corresponding 71 proj eets below bracket (3G is provided in order to coinpen- 120 sate for any inequalities `in said flanges. I

A modified form of compensating hinge joint is shown in Figs. 14 and 15, and eonthe height of sists of a supplementary arm 72 yhinged at 125 inoiuary arm 72 instead of the underside 136l This mechanism may 80 end each conveyor is and a backed slightly so as to permit the bobbins 13 to unwind as they are lowered and consequently prevent undue tension in the yarns or threads.

By means oi' handwlreel (50 an`d intermediate gearing the horizontal rack bars or slides 59 and the bar 55 are advanced until the forward limbs 54, 54, of each carrier 49 are presented beneath the mutually adjacent cap 7 as shown in Fig. 4, after which the conveyer mechanism is raised until the ends of the conveyers are above the caps 7 when the lever 44 is operated to move the levers or arms 47 and hence also the conveyers 63 a short distance inward after which the rockshaft 46 is moved longitudinally to the left; to disengage the conveyers 63 from the yarns or threads 462 and' when the conveyers are free therefrom the lever 44 is operated to oscillate the rod 43 in the reverse direction so as to swing the arms 47 and thread conveyers 63 outward when the whole of the eonveyer mechanism is raised by' turning handwheel 32 until the thread-conveyers are above the thread board 3, the thread-conveyers 63 being manipulated by turning handwheel 48 on shaft 46 until they rest on top of the thread board 3, as shown in Fig. (i. The handwheel is then turned to bring the carriers 49 forward until the caps 7 rest at the back of the carriers and above the circular portion of the keyholeshaped apertures in the base of same. The spindle rail 9 is lowered, by turning the handwheel 20, until the spindles 8 are completely withdrawn from within the caps 7 and the can riers 49 areA drawn back carrying the ca )s 7 with them away from above' the full bob ins 13. The full bobbins 13 have now to be removed from the tubes 11, and to effect this the spindle rail 9 is raised and after it the lifter plate 15 is also raised, bringing the full bobbins 1.3 level with and immediately in front. ot the caps 7. The carriers t9 are once more advanced and the forward limbs 54, 54, pass beneath the 't'ull bobbins 13 which are'seized by the auxiliary steadying spring-clips 51 and are retained upon the flanged forward limbs of carriers 49 immediately in front of their corresponding caps 7, as shown in Fig. 5. lhe spindle rail 9 and liftenplate 15 are then lowered to the bottomot' the frame in order to withdraw the spindles 8 and tubes 11 from within the full bobbinsl 13 and in orderto permit the carriers 49 to 'pass over the tops of tubes 11. After the spindles 8 Vhave been withdrawn from the full bobbins 13 the carriers supporting the latter together with the caps 7 are advanced until the central openings or bores of the full bobbins 13 are co-axial above the pegs 37, and the bar 35 is moved vertically upward by turning handvfheel 31 in 'a coiinter-cloclmvise direction until the pegs 37 are well inserted in the central openings of the full bobbins 13. The carriers 49 are then withdrawn, thus releasing the full bobbins 13 from the retaining spring-clips 51 and allowing the full bobbins 13 todi-op freely on to the pegs 37. After the full bobbins 13 have been transferred to the pegs 37 the handwheel 31 is turned still farther in a colmteicloekwise direction in order t0 raise the bar 36 and pegs 33 withl thewempty bobbins 14 upon them until thledatter are in front of the caps 7 and level with thehorizontal forward members or limbs 54 of carriers 49. The carriers 49 are then advanced once more until the forward limbs 54 pass beneath the lower extremities of the empty bobbins 14 which are seized and held lightly by the spring clips 51 which retain the empty bobbins 14 upon the carriers 49 in front of the caps 7, as shown in Fig. G. These spring-clips 51 serve as auxiliary steadying devices for the full and empty bobbins respectively when restin upon the carriers in front of the caps and when being transferred from the spindles to the pegs or vice versa, and .the spring-clips do not grip the caps 7 but are arranged to surround the same loosely. As has been stated above, the empty bobbins 14 are now resting upon the flanged forward limbs 54 of the carriers 49, and in order that said empty bobbins may be set in place upon the driving,r spindles 8, the bar 36 is lowered to withdraw the pegs 38 from within the empty bobbins and the carriers now holding` the caps and empty bobbins are drawn back until the central openings or bores of the 'empty bobbins 1-'1 are co-axially above the driving spindles 8 and tubes 11. By tnrniner hand wheel 20 ,the spindle rail 9 is raised andthe spindles 8 and tubes 11 are inserted in the empty bobbins 14. The carriers 49 are then further withdrawn permitting the empty bobbins 14 to fall freely onto the driving spindles 8 and tubes 11, and then the spindle-rail 9 is lowered and the carriers 49 are once more advanced, bringing the caps 7 into position above the empty bobbins 14 after which the spindles are raised to the normal position within the empty bobbins and are inserted in the caps.

Vhen the ca ps have been placed upon the spindles the litter-plate 15 is raised in order to carry the empty bobbins 14 up through the circular'apertures ot' the slots in carriers 49 and into the cups, and the carriers 49 are then withdrawn slightly so as to place the flanged forward limbs 54 beneath the empty bobbins 14 which are caused to rest. thereupon, as shown in Fig. 8, by lowering the lifter-plate l5.

The next step is to place the lengths of yarn or thread (32 extending between th t'nll bobbins 13 and the nip of each sel1 ot drawing rollers 2, Q, on to the tops of the driving pegs 12, 12, of each tube Il, as shown in Fig. 8. In order to ett'ect this J. H. SMEDLEY.
